Describe the relationship between the values of ΔG, Keq, and the direction that a reaction will spontaneously proceed.

ΔG is related to Q by the equation ΔG=RTlnQK. If ΔG < 0, then K > Q, and the reaction must proceed to the right to reach equilibrium. If ΔG > 0, then K < Q, and the reaction must proceed to the left to reach equilibrium. If ΔG = 0, then K = Q, and the reaction is at equilibrium.
oop! typo. That should be dG = - RTlnK
